Torque for Bolts, Nuts and Taperlock Studs
Be very careful never to mix metric with customary (standard) fasteners. Mismatched or incorrect fasteners will cause engine damage or malfunction and may even result in personal injury. Original fasteners removed from the engine should be saved for reassembly whenever possible. If new fasteners are needed, they must be of the same size and grade as the ones that are being replaced.
The material strength identification is usually shown on the bolt head by numbers (10.9, etc.). The following chart gives general torques for bolts and nuts with Grade 10.9. This product uses 10.9 Grade metric fasteners. Use these standard torque values unless otherwise specified in this publication.Torque for Bolts and Nuts With Metric Threads

Torque for Hose Clamps - Standard Worm Drive Band Type
The following chart gives the torques for initial installation of hose clamps on new hose and for reassembly or retightening of hose clamps on existing hose.
Torque for Constant Torque Hose Clamps
A constant torque hose clamp can be used in place of any standard hose clamp.Make sure the constant torque hose clamp is the same size as the standard clamp.Due to extreme temperature changes, hose will heat set. Heat setting causes hose clamps to loosen. Loosened hose clamps can result in leaks. There have been reports of component failures caused by hose clamps loosening. The new, constant torque hose clamp will help prevent these failures.Installation
Each installation application can be different depending on the type of hose, fitting material and anticipated expansion or contraction of the hose and fittings. A torque wrench should be used for proper installation of the new, constant torque hose clamps. Constant torque hose clamps should be installed as follows: To allow for maximum expansion, install clamps at 5.7 N m (50.00 lb in).To allow for equal expansion or contraction, install clamps at 10.2 N m (90.00 lb in).To allow for maximum contraction, install clamps at 14.1 N m (125.00 lb in).
